noons'rora 7 Application filed Novembe1"16,. 1926. Serial No. 148.663.

This invention relates to door stops and has particular reference to a stop which. provides means for holding. a door in an open position.

ObJGCf/S of the mventmn are to provide a device: of simple, durable construction which may be manufactured at alow cost and which inuse will provide efiicient' means for. receiv-, ing a door and holding the same in an open.-

position, Y i

A'further object is1t0 provide a door stop: and holding device-which may be: stamped from one pieceof metal and which-may be quickly and conveniently attached to a floor or structure. and operatively secured in position. I An additional object is to provide a door holder which willact as a stop and prevent the door from being brought into contact with the wall when it is moved to an open position and which may be employed on doors hinged to either the right or the left side of the door opening.

The above objects are accomplished and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompaying drawing wherein I have shown a preferred form of the invention, it being understood that the invention is capable of various adaptations and that changes and modifications may be made or resort had to substitutions which come within the scope of the claims hereunto appended.

In the drawings likecharacters of reference are employed to designate like parts as the same appear in any of the several views and in which Figure 1 is a top plan view of a door stop constructed in accordancewith this invention,

Figure 2 is a perspective view of same, Figure 3 is a horizontal, sectional view of a portion of a door and showing a plan view of the stop to illustrate the position thereof when the do'oris swung to or from the stop, Figure 4 is a sectional view also taken as indicated by the line 4-4 of Figure 5 and illustrating the door as it is received in the holder,

Figure 5 is a perspective view showing the lower portion of a door as the same is held in an open position by a holder constructed in accordance with this invention.

Proceeding now to a detailed description trally thereof.

ofthe invention with referenceto theiadaptationthereof disclosed in the drawings, the, door is indicated by the numeral 6; My im-- proved holder is. preferably constructed of one piece of sheet metal having a fiat central.

portion or bottom wall 7, The metal ois turned upwardly 01101313081136 sides thereof to" provide the side walls 8 and 9. Thebottom wall is substantiallyrectangular in form and is enlarged adjacent each open end there-- of. The side walls 8 and 9 are curved outwardly adjacenteach open end of the device for a purpose presently to appear. 1 The bottom plate '7 is provided in close spaced rela-- tion to the rear wall 8 thereof at points ads, jacent each open end thereof with an opening or bore 11 which extends therethrough. The bottom plate is also provided centrally thereof with an opening 12 which is prefer. ably circular in form and is positioned cen- The numeral 13 denotes a screw, pin or other holding member which is positioned in one of the bores 11 to secure the device to the floor or other supporting structure. The numeral 14 denotes a pin which is also secured in the floor or support ing structure and which is entered in the opening 12 to limit the rotary movement of the plate 7 on the screw or pin 13.

In use, the door 6 is swung to its open position; The stop is placed on the floor as shown in Figure 3 in a position in which the door will swing free of the upturned edge 9. The screw 13 is then placed in the opening 11 which is adjacent the end'which is presented away from the door. The screw or pin 13 is then driven or otherwise secured in the floor or other supporting structure and the pin 14 is secured in the floor so as to project into the opening 12 and contact with that side of the opening nearest the wall.

It willbe noted that in case the door is hinged to the opposite side of the opening, the screw or pin 13 will be entered in the other bore 11 and the device likewise secured in position. Thebores 11 are slightly larger than the body of the screw or pin 13 whereby the plate 7 may be given a rotary movement thereon.

It will be noted by reference to Figure. 3 that the door when swung to its full open position will not contact with the up-turned wall 9 and that the door may be forced against the outwardly curved end portion of the wall 8 as the door is then forced to its full open position. As the door is moved to its open position, it will cause a rotary movement of the plate 7 and bring the upturned portion 9 to the position shown in Figure 4. If the door is forced toward a closed position, the outer edge thereof will contact with the wall 9 whereby it will be firmly heldsby said wall 9 from a closing movement. JVhen it is desired to close the door, the wall 9 is engaged and swung to the position shown in Figure 3,-thus forcing the door outwardly and permitting it to swing clear of the up turned portion 9. V

It will be noted that as the door is swung toward a closed position, the plate 7 is automatically positioned to receive the door when it is again swung to a full open position.

Having thus illustrated my invention, what I claim as new and desire to secure by Letters Patent is 1. In a device of the class described, a channel member, the side walls thereof'flared outwardly adjacent each end thereof, means positioned adjacent one corner of the bottom wall'of said member to rotatably secure the same to a supporting structure and means to limit the rotary movement of said member.

2. In a devicevof the class described, a plate, a flange projecting upwardly from opposite sides thereof, each of'said flanges flaring outwardly adjacent each end thereof, said plate provided with an opening adjacent one corner thereof and means insert-ible in said opening for rotatably securing said plate to a supporting structure.

3. In a device of the class described, a plate, a flange projecting upwardly from opposite sides thereof, each of said flanges flaring outwardly adjacent each end thereof said plate provided with an opening adjacent one corner thereof; means insertible in said opening for rotatably securing said plate to a supporting structure, said plate also provided with a centrally positioned opening and a pin secured to said supporting structure and projecting into the last named opening to limit the rotarymovementof said plate.

In testimony whereof I have hereunto set my hand. I

WILLIAM I. ALLISON.
